Is this plastic mesh underneath my grass toxic?

Hi everyone, I have a raised vegetable on my lawn but later found that there is a green mesh underneath the grass. My question is whether is mesh/net is toxic and whether I have to remove the net/mesh before I grow vegetables on the raised garden bed.
It’s probably not toxic. Plastics take forever to break down. That said, it wouldn’t take too long to cut away and remove it from the area under your raised beds. For peace of mind.
From what I have read, no, it is not toxic and should be fine.
no it is not toxic I asked a plant grower and he said they use it and have for years and nothing to hurt your beds or soil
Hi Clement,
I shouldn't think so, More likely to have been put there to stop animals coming in or going out through the ground.
Looks like a barrier for burrowing animals, it should not be toxic. I would leave it in place thinking it has a purpose. Your raised beds might be better off with it there.
That is a barrier for small animals that dig. It is not toxic to your garden. You can always take it out if you do not want it there.
Thanks everybody for the input. I think I am going to leave it as I have two 4'x16' vegetable beds, it would be a LOT of work to remove the soil, then the net, then put the soil back. Thanks again!
I doubt it
Clement,
Any potential toxicity of plastic is activated only at extremely high temperatures, such as in a situation where the plastic is burning and expelling fumes.
You have nothing to worry about here.
No it's not. Actually it's part of a grass seeded mat. it's basically used on inclines or where grass seed would either be washed away or where seed wouldn't grow. I've seen it used along highways where the ground slopes up. Municipalities use it on parkways when they are replacing street curbs. It has become available to the public. Cheaper than sod and less care than grass seed. It also comes dyed green for visual impact.
I’ve seen sod with this.
YES this plastic is backing for the grass as it is harvested into smaller chunks to be sold and
laid down for instant lawns.
it is a barrier for small animals
Our new neighborhood has it everywhere. We have nothing but sand and this mesh was used to hold the grass in place while the sod took. However, two years later it's a royal pain as it pops up in the strangest places and sandeled feet get caught up in it causing a tripping hazard. It does nothing to stop burrowing animals. Just ask our ground hog. 😜
Hi Clement, this is just barrier to keep critters from digging around in your garden and lawn, it is not toxic and it will protect your plants from pests.
